“BDA approved” sounds precise. In a sales conversation it can be anything but. The useful question is: which document, issued by which authority, approves which plan?
Separate the authority from the adjective
Ask the seller to show the sanction or approval record, not just a logo, certificate heading or brochure statement. Confirm the legal authority that had jurisdiction on the relevant date.
Match the plan to the ground
The plot number, survey references, roads, civic spaces and dimensions on the sanctioned plan should correspond to the site being offered.

Phrases that need a follow-up
“BDA limits” — location is not approval.
“BDA release” — ask what was released and under which record.
“BDA NOC” — ask what the NOC covers; an NOC is not automatically layout approval.
“Approval under process” — treat this as not yet approved.
What to do with the record
Have your lawyer verify the document and its applicability. Where official verification is available, compare the copy against the issuing authority’s record.
